Hi! I try to use surface color in python, but I haven’t understood the example in documentation. May someone helps me? surf =go.Surface(x=X1,y=Y1,z=Z1, surfacecolor=intensity) X1, Y1, Z1 are two-dimensional arrays. intensity – three-dimensional array, first and second idexes correspond to X1 and Y1, third is for RGB: intensity[:,:,0] is for red, intensity[:,:,1] is for green and intensity[:,:,2] is for blue. What should I do to assign RGB numbers to surfacecolor? Thanks in advance! ---

Hi @vanis, Surface traces are colored by mapping the `surfacecolor` numeric values to colorsing using the current colorscale. So you’ll need to pass something to the `surfacecolor` property that is a 2D array of numbers that has the same 2D shape as `x` `y` and `z`. Then this will get mapped to colors according to the colorscale specified in the `colorscale` property. Hope that helps clear things up, -Jon ---

Thanks, I’ve got it)
